Alex Wong

One of So You Think You Can Dance's early front-runners, Alex Wong, may be out of the competition for good after sustaining a foot injury during rehearsals.

Wong, 23, ruptured his Achilles tendon during rehearsals with partner Adechike Torbert on Tuesday and was unable to perform on Wednesday's episode. Per the dance competition's revised rules, Wong will automatically be put in the Bottom 3 and face a possible elimination on Thursday's episode.

A source close to the show tells TVGuide.com Wong plans to see a doctor sometime before Thursday's episode, in order to determine the extent of his injury and how much time he'll need to fully recover.

A Vancouver native, Wong was most recently a principal soloist with the Miami City Ballet before making into Dance's top 11.
